Chennai Kathipara Bridge

Chennai (, ), formerly known as Madras ( the official name until 1996), is the capital city of Tamil Nadu, the southernmost Indian state. The largest city of the state in area and population, Chennai is located on the Coromandel Coast of the Bay of Bengal.

According to the 2011 Indian census, Chennai is the sixth-most populous city in the country and forms the fourth-most populous urban agglomeration. The Greater Chennai Corporation is the civic body responsible for the city; it is the oldest city corporation of India, established in 1688—the second oldest in the world after London. The city of Chennai is coterminous with Chennai district, which together with the adjoining suburbs constitutes the Chennai Metropolitan Area, the 36th-largest urban area in the world by population and one of the largest metropolitan economies of India.

The traditional and de facto gateway of South India, Chennai is among the most-visited Indian cities by foreign tourists. It was ranked the 43rd-most visited city in the world for the year 2015 and was ranked the 36th-most visited city in the world for the year 2019. The Quality of Living Survey rated Chennai as the safest city in India. Chennai attracts 45 percent of health tourists visiting India, and 30 to 40 percent of domestic health tourists. As such, it is termed "India's health capital". An established port of trade of British India since the 1600s, Chennai has the fifth-largest urban economy, and had the third-largest expatriate population in India, at 35,000 in 2009, 82,790 in 2011 and estimated at over 100,000 by 2016. Tourism-guide publisher Lonely Planet named Chennai as one of the top ten cities in the world to visit in 2015.

Chennai is ranked as a beta-level city in the Global Cities Index, and was ranked the best city in India by ''India Today'' in the 2014 annual Indian city survey. In 2015 Chennai was named the "hottest" city (city worth visiting and worth living in for long term) by the BBC, citing the mixture of both modern and traditional values. National Geographic mentioned Chennai as the only South Asian city to feature in its 2015 "Top 10 food cities" list. Chennai was also named the ninth-best cosmopolitan city in the world by Lonely Planet. In October 2017, Chennai was added to the UNESCO Creative Cities Network (UCCN) list for its rich musical tradition. More than one-third of India's automobile industry is based in the city. Home to the Tamil film industry, Chennai is also known as a major film production centre. It is one of the 100 Indian cities to be developed as a smart city under the Smart Cities Mission.

Etymology

The name ''Chennai'' is of Telugu language origin. It was derived from the name of a Telugu ruler, Damarla Mudirasa Chennappa Nayakudu, father of Damarla Venkatapathy Nayak, a Nayak ruler who served as a general under Venkata III of the Vijayanagara Empire from whom the British acquired the town in 1639. The first official use of the name ''Chennai'' is said to be in a sale deed, dated August 1639, to Francis Day of the East India Company, even before the Chennakesava Perumal Temple was built in 1646, while some scholars argue to the contrary.

The name ''Madras'' is also of native origin, and has been shown to have been in use before the British established a presence in India. A Vijayanagara-era inscription dated to the year 1367 that mentions the port of Mādarasanpattanam, along with other small ports on the east coast, was discovered in 2015 and it was theorised that the aforementioned port is the fishing port of Royapuram. According to some sources, ''Madras'' is derived from Madraspattinam, a fishing village north of Fort St George. However, it is uncertain whether the name was in use before the arrival of Europeans. British military mapmakers believed Madras was originally ''Mundir-raj'' or ''Mundiraj,'' which was the name of a Telugu community, Mudiraj, who were the native inhabitants of the city.

There are also suggestions that it may have originated from the Portuguese phrase ''Mãe de Deus'' or ''Madre de Dios'', which means "mother of God", due to Portuguese influence on the port city, specifically referring to a Church of St. Mary.

In August 1996, the Government of Tamil Nadu officially changed the name from ''Madras'' to ''Chennai''. At that time many Indian cities underwent a change of name. However, the name ''Madras'' continues in occasional use for the city, as well as for places named after the city such as University of Madras, IIT Madras, Madras Institute of Technology, Madras Medical College, Madras Veterinary College, Madras Christian College.

History

Stone age implements have been found near Pallavaram in Chennai. According to the Archaeological Survey of India (ASI), Pallavaram was a megalithic cultural establishment, and pre-historic communities resided in the settlement.

The region around Chennai has served as an important administrative, military, and economic centre for many centuries. During the 1st century CE, a poet and weaver named Thiruvalluvar lived in the town of Mylapore (a neighbourhood of present Chennai). From the 1st–12th century the region of present Tamil Nadu and parts of South India was ruled by the Cholas.

The Pallavas of Kanchi built the areas of Mahabalipuram and Pallavaram during the reign of Mahendravarman I. They also defeated several kingdoms including the Cheras, Cholas and Pandyas who ruled over the area before their arrival. Sculpted caves and paintings have been identified from that period. Ancient coins dating to around 500 BCE have also been unearthed from the city and its surrounding areas. A portion of these findings belonged to the Vijayanagara Empire, which ruled the region during the medieval period.

The Portuguese first arrived in 1522 and built a port called ''São Tomé'' after the Christian apostle, St. Thomas, who is believed to have preached in the area between 52 and 70 CE. In 1612, the Dutch established themselves near Pulicat, north of Chennai.

On 20 August 1639 Francis Day of the East India Company along with the Nayak of Kalahasti Damarla Chennappa Nayakudu, travelled to the Chandragiri palace for an audience with the Vijayanager Emperor Peda Venkata Raya. Day was seeking to obtain a grant for land on the Coromandel coast on which the company could build a factory and warehouse for their trading activities. He was successful in obtaining the lease of a strip of land about long and inland in return for a yearly sum of five hundred lakh pagodas. On 22 August, he secured the land grant from local Nayak ( Damarla Venkatadri Nayaka and his younger brother Aiyappa Nayaka of Poonamallee). The region was then formerly a fishing village known as "Madraspatnam". A year later, the Company built Fort St. George, the first major English settlement in India, which became the nucleus of the growing colonial city and urban Chennai, grew around this Fort. Post independence the fort housed the Tamil Nadu Assembly until the new Secretariat building was opened in 2010, but shortly afterwards it was again moved back to Fort St. George, due to a change in the Government.

In 1746, Fort St. George and Madras were captured by the French under General La Bourdonnais, the Governor of Mauritius, who plundered the town and its outlying villages. The British regained control in 1749 through the Treaty of Aix-la-Chapelle and strengthened the town's fortress wall to withstand further attacks from the French and Hyder Ali, the Sultan of Mysore. They resisted a French siege attempt in 1759. In 1769 the city was threatened by Mysore and the British were defeated by Hyder Ali, after which the Treaty of Madras ended the war. By the 18th century, the British had conquered most of the region around Tamil Nadu and the northern modern–day states of Andhra Pradesh and Karnataka, establishing the Madras Presidency with Madras as the capital.

Gradually, the city grew into a major naval base and became the central administrative centre for the British in South India. The city served as the baseline for the Great Trigonometrical Survey of India started on 10 April 1802.Gill, B. (2001); "THE BIG MAN.

8 March 2016. With the advent of railways in India in the 19th century, the thriving urban centre was connected to other important cities such as Bombay and Calcutta, promoting increased communication and trade with the hinterland. Sir Arthur Lawley was Governor of Madras from 1906 to 1911 and promoted modern agriculture, industry, railways, education, the arts and more democratic governance. The Governor lived in Government House, Fort St George, and had a country home at Guindy, with access to a golf course, hockey pitches, riding stables and the Guindy Horse Racing Track.Sir Arthur Lawley, Eloquent Knight Errant, Chapter 6. Catastrophe, Conspiracy, Celebration. The Benefits of Empire, Lady Lawley Cottage (Western Australian Red Cross) 2008 iBookNotes on the Administration of Sir Arthur Lawley, Governor of Madras, 1906–1911. Madras Government Press, 1912 In the First World War as Red Cross Commissioner in Mesopotamia, he looked after the welfare of Indian soldiers.A Message from Mesopotamia, Sir Arthur Lawley, Hodder and Stoughton, London. 1917. Madras was the only Indian city to be attacked by the Central Powers during World War I, when an oil depot was shelled by the German light cruiser on 22 September 1914, as it raided shipping lanes in the Indian Ocean, causing disruption to shipping.

After India gained its independence in 1947, the city became the capital of Madras State, which was renamed as Tamil Nadu in 1969. The violent agitations of 1965 against the compulsory imposition of Hindi and in support of English in India in the state marked a major shift in the political dynamics of the city and eventually it had a big impact on the whole state. Because of Madras and its people, English was not abolished as an official language, and remains an official language of India alongside Hindi. On 17 July 1996, the city known as Madras was officially renamed Chennai, in line with what was then a nationwide trend to using less Anglicised names. On 26 December 2004, an Indian Ocean tsunami lashed the shores of Chennai, killing 206 people in Chennai and permanently altering the coastline. The 2015 Chennai Floods submerged major portions of the city, killing 269 people and resulting in damages of .

Geography

Chennai is located on the south–eastern coast of India in the north–eastern part of Tamil Nadu on a flat coastal plain known as the Eastern Coastal Plains. Its average elevation is around , and its highest point is . Chennai is south of Delhi, southeast of Mumbai, and southwest of Kolkata by road. Two major rivers flow through Chennai, the Cooum River (or ''Koovam'') through the centre and the Adyar River to the south. A third river, the Kortalaiyar, travels through the northern fringes of the city before draining into the Bay of Bengal, at Ennore. The estuary of this river is heavily polluted with effluents released by the industries in the region. Adyar and Cooum rivers are heavily polluted with effluents and waste from domestic and commercial sources, the Coumm being so heavily polluted it is regarded as the city's eyesore. A protected estuary on the Adyar forms a natural habitat for several species of birds and animals. The Buckingham Canal, inland, runs parallel to the coast, linking the two rivers. The Otteri Nullah, an east–west stream, runs through north Chennai and meets the Buckingham Canal at Basin Bridge. Several lakes of varying size are located on the western fringes of the city. Some areas of the city have the problem of excess iron content in groundwater.

Chennai's soil is mostly clay, shale and sandstone. Clay underlies most of the city, chiefly Manali, Kolathur, Maduravoyal, K. K. Nagar, Tambaram, Mudichur, Pallavaram Semmencherry, Alapakkam, Vyasarpadi and Anna Nagar. Sandy areas are found along the river banks and coasts, and include areas such as Tiruvottiyur, George Town, Madhavaram, New Washermanpet, Chepauk, Mylapore, Porur, Adyar, Besant Nagar and Uthandi. In these areas, rainwater runoff percolates quickly through the soil. Areas having hard rock surface include Guindy, Nanganallur, Pallikaranai, Alandur, Jaladampet, Velachery, Adambakkam and a part of Saidapet and Perungudi. The ground water table in Chennai is at 4–5 m below ground in most of the areas, which was considerably improved and maintained through the mandatory rain water harvesting system. Of the 24.87 km coastline of the city, 3.08 km experiences erosion, with sand accretion along the shoreline can be noticed at the Marina beach and the area between the Ennore Port and Kosasthalaiyar river.

Geology

Chennai is classified as being in Seismic Zone III, indicating a moderate risk of damage from earthquakes. Owing to the geotectonic zone the city falls in, the city is considered a potential geothermal energy site. The crust has granite rocks indicating volcanic activities in the past. It is expected that temperatures of around 200 to 300 C° will be available if the ground were drilled 4 to 5 km deep. The region has the oldest rocks in the country dating back to nearly a billion years.

Flora and fauna

The southern stretch of Chennai's coast from Tiruvanmiyur to Neelangarai are favoured by the endangered olive ridley sea turtles to lay eggs every winter. A large number of cattle egrets, pond herons and other waterbirds can be seen in the rivers of Cooum and Adyar. About 75,000 birds migrate to Chennai every year. Marshy wetlands such as Pallikaranai also play host to a number of migratory birds during the monsoon and winter. Over 300 species of birds have been recorded in the city and its neighbourhood by members of Madras Naturalists' Society since its inception in 1978.

Guindy National Park is a protected area within the city limits. Wildlife conservation and research activities take place at
Arignar Anna Zoological Park including olive ridley sea turtle conservation. Madras Crocodile Bank Trust is a herpetology research station, located south of Chennai. The city's tree cover is estimated to be around 64.06 sq km. The most dominant tree species is the copper pod, followed by Indian beech and Neem. A total of 121 species of trees belonging to 94 genera and 42 families are found in the city. Nearly half of the native plant species in the city's wetlands have disappeared in recent years. The city, which had 85 percent of its area covered with aquatic plants until the 1970s, now has only 25 percent of its area covered with such plants.

Environment conservation

Chennai has three rivers and many lakes spread across the city. Urbanization has led to the shrinkage of water bodies and wetlands. The quantity of wetlands in the city has decreased from 650 to only 27 currently. The Chennai River Restoration trust set up by the government is working on the restoration of Adyar river. Environmentalist Foundation of India is a volunteering group working towards wildlife conservation and habitat restoration.

The encroachment of urban development on wetlands has gravely hampered the city's sustainability, and contributed both to the city's floods in 2015 and water scarcity crisis in 2019.

Climate

Chennai has a dry-summer tropical wet and dry climate under the (Köppen climate classification). The city lies on the thermal equator and is also on the coast, which prevents extreme variation in seasonal temperature. The hottest part of the year is late May to early June, known regionally as ''Agni Nakshatram'' ("fire star") or as ''Kathiri Veyyil'', with maximum temperatures around . The coolest part of the year is January, with minimum temperatures around . The lowest recorded temperature was on 11 December 1895 and 29 January 1905. The highest recorded temperature was on 31 May 2003. The average annual rainfall is about .

The city gets most of its seasonal rainfall from the north–east monsoon winds, from mid–October to mid–December. Cyclones in the Bay of Bengal sometimes hit the city. The highest annual rainfall recorded is in 2005. Prevailing winds in Chennai are usually southwesterly between April and October and north-easterly during the rest of the year. Historically, Chennai has relied on the annual rains of the monsoon season to replenish water reservoirs, as no major rivers flow through the area. Chennai has a water table at 2 metres for 60 percent of the year.

NE monsoon

The city of Chennai is located on the east coast of India, which is also known as the Coromandel Coast.
Chennai is largely dependent on NE monsoon, since 65% of rains are received in this season. Cyclones and depressions are common features during the season. Cyclones, in particular, are especially unpredictable. They may even move towards Orissa, west Bengal, Bangladesh, and also Myanmar. The season between October and December is referred as the NE monsoon period. Floods are common during this period. In 2015 Chennai received record-breaking rains since 1918, which caused massive floods.

Land usage

As of 2018, the city had a green cover of 14.9 percent, against the World Health Organization recommendation of 9 square metres of green cover per capita in cities. The city had a built-up area of 71 percent. Waterbodies cover an estimated 6 percent of the total area, and at least 8 percent of the area has classified as open space. As of 2017, the total volume of water harvested was 339 mcft and groundwater recharge was 170 mcft.

Administration

Chennai city is governed by the Greater Chennai Corporation (formerly "Corporation of Madras"), which was established in 1688. It is the oldest surviving municipal corporation in India and the second oldest surviving corporation in the world. In 2011, the jurisdiction of the Chennai Corporation was expanded from to an area of , dividing into three regions—North, South and Central, which covers 200 wards. The corporation is headed by a mayor, an office presently occupied by Priya Rajan. The Mayor and councillors of the city are elected through a popular vote by the residents. While the city limit was expanded in 2011, the revised population is yet to be officially announced.

The Chennai Metropolitan Development Authority (CMDA) is the nodal agency responsible for planning and development of Chennai Metropolitan Area, which is spread over an area of , covering the Chennai district and parts of Tiruvallur, Kanchipuram and Chengalpattu districts. The larger suburbs are governed by town municipalities and the smaller ones are governed by town councils called panchayats. Under the gamut of the CMDA are 5 parliamentary and 28 assembly constituencies. The CMDA has drafted an additional Master Plan that aims to develop satellite townships around the city. The city's contiguous satellite towns include Mahabalipuram in the south, Chengalpattu and Maraimalai Nagar in the southwest, and Sriperumpudur, Arakkonam, Kanchipuram and Tiruvallur to the west.

Chennai, as the capital of the state of Tamil Nadu, houses the state executive and legislative headquarters primarily in the Secretariat Buildings in the Fort St George campus. The Madras High Court, is the highest judicial authority in the state, whose jurisdiction extends across Tamil Nadu and Puducherry. Chennai has three parliamentary constituencies—Chennai North, Chennai Central and Chennai South—and elects 24 Members of the Legislative Assembly (MLAs) to the state legislature.

Law and order

The Greater Chennai Police is the main law enforcement agency in the city, with a jurisdiction of over catering to over 8.5 million people. It consists of 121 police stations and is headed by a commissioner of police. The Greater Chennai Police is a division of the Tamil Nadu Police, and the administrative control lies with the Tamil Nadu Home Ministry. Chennai City Traffic Police (CCTP) is responsible for the traffic management in the city. The metropolitan suburbs are policed by the Chennai Metropolitan Police, headed by the Chennai Police Commissionerate, and the outer district areas of the CMDA are policed by the Kanchipuram and Thiruvallur police departments.

(prior to the expansion of Chennai Corporation area), Chennai city has a sanctioned strength of 14,000 police personnel. With a population density of 26,903 persons per square kilometre, the city had 1 policeman for every 413 people. The Chennai suburban police had about 4,093 police personnel and a ratio of 1:1,222. In 2010, the crime rate in the city was 169.2 per 100,000 people, as against an average of 341.9 in the 35 major cities of India. In 2011, North Chennai zone had 30 police stations and 3 police out posts, Central Chennai zone had 28 police stations and 3 police out posts, and South Chennai zone had 30 police stations.

In 2009, Madras Central Prison, one of the oldest prisons in India, built over of land, was demolished; the prisoners were moved to Puzhal Central Prison.

Politics

Since the 19th century, when Western scholars proposed that Dravidian languages, which dominated the southern region of India, formed a different linguistic group to that of the Indo-Aryan languages that are predominant in the north of the subcontinent, the aspects of Tamil nationalism gained prominence. This resulted in the Anti-Hindi agitations in the city and across the state. However, the post-Independence re-organisation of Indian states according to linguistic and ethnic basis has moderated Tamil nationalism, especially the demand for separation from the Indian Union. The Anti-Hindi agitations in mid-1960s made the DMK more popular and more powerful political force in the state. The agitations of the 1960s played a crucial role in the defeat of the Tamil Nadu Congress party in the 1967 elections and the continuing dominance of Dravidian parties in Tamil Nadu politics.

Being the capital of the Madras Province that covered a vast area of the Deccan region, Chennai remained the centre of politics in the southern region of India during the British colonial era. After Independence, it remained the centre of political activities of the state of Tamil Nadu. Chennai is the birthplace of the idea of the Indian National Congress, commonly known as the Congress Party. Founded by Indian and British members of the Theosophical Society movement, most notably A.O. Hume,Theosophy and the Origins of the Indian National Congress

/ref> During the first 50 years of the Indian National Congress, the city played host to its conferences seven times in 1887, 1894, 1898, 1903, 1908, 1914 and 1927, becoming one of the strong bases for the Indian independence movement. After independence, the city hosted the Congress in 1955 in its suburb of Avadi.

Chennai is also the birthplace of several regional political movements since the British era. South Indian Welfare Association, one of the earliest regional parties, was founded in 1916, which later came to be known as the Justice Party, which was the main opposition party to the Indian National Congress in the state. In 1944, the party was renamed Dravidar Kazhagam (DK) by E. V. Ramasami (popularly known as 'Periyar'). The party was a non-political party that demanded the establishment of an independent state called Dravida Nadu. However, due to the differences between its two leaders Periyar and C. N. Annadurai, the party was split. Annadurai left the party to form the Dravida Munnetra Kazhagam (DMK). The DMK decided to enter into politics in 1956.

Utility services

The city's water supply and sewage treatment are managed by the Chennai MetroWater Supply and Sewage Board. Water is drawn from Red Hills Lake and Chembarambakkam Lake, the primary water reservoirs of the city, and treated at water treatment plants located at Kilpauk, Puzhal, Chembarambakkam and supplied to the city through 27 water distribution stations. The city receives 530 million liters per day (mld) of water from Krishna River through Telugu Ganga project, 180 mld of water from the Veeranam lake project and 100 mld of water from the Minjur desalination plant, the country's largest sea water desalination plant. However, Chennai is predicted to face a huge deficit of 713 mld in 2026 as the demand is projected at 2,248 mld and supply estimated at only 1,535 mld. The city's sewer system was designed in 1910, with some modifications in 1958. There are 714 public toilets in the city managed by the city corporation, and 2,000 more have been planned by the corporation. The corporation also owns 52 community halls across the city.

The Corporation of Chennai provides civic services to the city. Garbage collection in some of the wards is contracted to Ramky Enviro Engineers Limited, a private company, while the Corporation looks after the removal and processing of solid waste in the others, with a superintendent engineer managing the channels. , eight transfer stations exist within the city for treating the waste. Garbage is dumped in two dump-yards in the city—One in Kodungaiyur and another in Pallikaranai, with a major portion of the latter covering the Pallikaranai marshland. In market areas, the conservancy work is done during the night. Electricity is distributed by the Tamil Nadu Electricity Board. Fire services are handled by the Tamil Nadu Fire and Rescue Services. The city, along with the suburbs, has 33 operating fire stations.

The Chennai City region has 568 post offices, of which nearly 460 operate from rented premises.

Architecture

With the history of many neighbourhoods of the city such as Mylapore, Triplicane, and Tiruvanmiyur antedating that of the city itself, the architecture of Chennai ranges in a wide chronology. The oldest buildings in the city date from the 7th and 8th centuries CE, which include the Kapaleeshwarar Temple in Mylapore and the Parthasarathy Temple in Triplicane, built in the Dravidian architecture. This architecture includes various styles, such as those of the Pallavas, the Cholas, and the Vijayanagara empires. The associated ''Agraharam'' architecture, which consists of traditional row houses surrounding a temple, can still be seen in these areas. The heritage temples at Mamallapuram at the outskirts of the city are some of the examples of the Pallava architecture. Chennai ranks second to Kolkata in having the largest collection of Indian heritage buildings in the country.

With the advent of the Mugals and the British, the city saw a rise in a blend of Hindu, Islamic and Gothic revival styles, resulting in the distinct Indo-Saracenic architecture. The architecture for several early institutions such as banking and commerce, railways, press and education, chiefly through the colonial rule, followed the earlier directions of the Neo-Classical and the Indo-Saracenic. The Chepauk Palace in the city, designed by Paul Benfield, is said to be the first Indo-Saracenic building in India. Since then, many of the colonial-era buildings in the city were designed in this style of architecture, which is most apparent around the Fort St. George built in 1640. Most of these were designed by English architects Robert Fellowes Chisholm and Henry Irwin. The best examples of this style include the Madras High Court (built in 1892), Southern Railway headquarters, Ripon Building, Government Museum, Senate House of the University of Madras, Amir Mahal, Bharat Insurance Building, Victoria Public Hall and the College of Engineering. The Triumph of Labour, also known as the Labour statue, at the Marina Beach is an important landmark of Chennai.

The construction of the National Art Gallery in Madras was completed in 1909. The new building, with a distinct façade, was built of pink sandstone brought from Sathyavedu, and formed part of the Madras Museum campus. It was opened, on 23 January 1909, by the Governor of Fort St. George, Sir Arthur Lawley, and called the Victoria Memorial Hall after the Queen-Empress Victoria."New for Old". Frontline. Volume 20 – Issue 14, 5 to 18 July 2003. India's National Magazine from publishers of the Hindu.Sir Arthur Lawley, Eloquent Knight Errant, Chapter 6. Catastrophe, Conspiracy, Celebration. The Benefits of Empire. Lady Lawley Cottage (Western Australian Red Cross) 2008 iBooksSir Arthur Lawley's Photo Album, Empire and Commonwealth Museum The residential architecture in the city was based on the bungalow or the continuous row house prototypes. Gothic revival style buildings include the Chennai Central and Chennai Egmore railway stations. The Santhome Church, which was originally built by the Portuguese in 1523 and is believed to house the remains of the apostle St. Thomas, was rebuilt in 1893 in neo-Gothic style.

By the early 20th century, the art deco too made its entry upon the city's urban landscape. From the 1930s onwards, many buildings in George Town were built in this style, including the United India building (presently housing the Life Insurance Corporation of India (LIC)) and the Burma Shell building (presently the Chennai House), both built in the 1930s, and the Dare House, built in 1940. Other examples include the Bombay Mutual building (presently housing LIC) and the South Indian Chamber of Commerce building. After Independence, the city witnessed a rise in the Modernism style of architecture. The completion of the LIC Building in 1959, the tallest building in the country at that time, marked the transition from lime-and-brick construction to concrete columns in the region. The presence of the weather radar at the Chennai Port, however, prohibited the construction of buildings taller than 60 m around a radius of 10 km for several decades that followed. In addition, the floor-area ratio (FAR) in the central business district is also 1.5, much less than that of smaller cities of the country. This resulted in the city expanding horizontally, unlike other metropolitan cities where vertical growth was prominent. On the contrary, the peripheral regions, especially on the southern and south-western sides, began experiencing vertical growth with the construction of buildings up to 60 floors. Within the downtown area, the 48-storied Highliving District Tower H remains the tallest building at 161 metres.

Demographics

Population

A resident of Chennai is called a ''Chennaite''. According to 2011 census, the city had a population of 4,646,732, within an area of 174 square kilometres administered by the Municipal Corporation, working out a population density of 26,705 persons per square kilometre; that had 11 lakh households, with 51% of them living in rented houses. The city's limits were expanded later in 2011 to 426 square kilometres and its population reached 7,088,000, resulting in a population density of 16,639 persons per square kilometre, with Chennai Municipal Corporation being renamed as Greater Chennai Corporation.

As of 2019, 712,000 families live below poverty line, which is about 40 percent of the 1.788 million families in the city.

Languages

Tamils form the majority of Chennai's population. English is spoken largely by white-collar workers, often mixed into Tamil. In 2001, out of the 2,937,000 migrants (33.8% of its population) in the city, 61.5% were from other parts of the state, 33.8% were from rest of India and 3.7% were from outside the country. As per the 2001 census, the number of speakers mother tongue wise are as follows, Tamil is spoken by 3,424,107 (78.8%), followed by Telugu by 419,209 (9.7%), Urdu
